<div class="textblock"><p>Represents the <a class="el" href="classshark_1_1_shape.html" title="Represents the Shape of an input or output.">Shape</a> of an input or output. </p>
<p>Mostly used for vector data, the <a class="el" href="classshark_1_1_shape.html" title="Represents the Shape of an input or output.">Shape</a> describes The expected structure of a model. A N-D shape with shape variables (n1,n2,..nN) expects an input of size n1*n2*...*nN which is then interpreted as tensor with the dimensionalities n1 x n2 x ... x nN. A batch of inputs is then treated as each element having this shape, so the batch size is not a part of the shape.</p>
<p>The standard shape is the 1-D shape just describing that a model interprets every input as 1-D input. A 0-D shape describes the inputs of a model where the input can not be described by a shape, for example a class label or other scalar values are 0d shapes. A 3-D shape could describe an image patch with rows x columns x channels.</p>
<p>Shapes can be flattened, this way a 3-D image patch can also be treated as a simple vector input.</p>
